In certain situations, a rotating chimney hood is the solution. Sometimes a chimney is not high enough or buildings have simply been built around the house over the years. Or a tree that has grown higher next to the house after a few years. It can then happen that a chimney gets overpressure in certain wind directions. In those cases, the Aspirotor stainless steel chimney hood can offer a solution. The Aspirotor stainless steel chimney hood is a wind-driven turbine with a maintenance-free ball bearing. The swing-away hinge mechanism provides easy access to the flue.
